WILSONVILLE – The Oregon Aviation Board approved a departure-only runway extension Thursday as part of the Aurora State Airport's master planning process. But a Federal Aviation Administration official said earlier this month that the agency wouldn't support a one-way extension.

The state board also adopted a longer, fallback option that would allow both takeoffs and landings, knowing the top choice would be a tough sell. That alternative comes at a price: it would close a road on the south end of the airport. The FAA will get its final say later this year.
